, Application December 21, 1931 Another object is tofprovide novelconnections between various elements within certain sections of abattery as well as between'elements in adjoining sections.

Another object is to provide interconnections between elements designedto facilitate the opening and inspection of a battery. 7 j Other'objects will appear from the following .description and appended claimsas well as from the accompanying drawing, in which- Fig. 1 is aperspective view of a battery partly broken away, to illustrate"connections between the elements within the housing of the battery, thetop of the battery having no outwardly extending connections except thetwo extreme ter-. minals of the whole battery.

Fig. 2 is a top plan view'of a battery, partly 525 broken away, showingconnections between elements within one and the same section and fromone sectionto anadjoining section.

single element showing the connecting lug.

Fig. 4 is a fragmentary side elevation of an element with a larger andwider lug for connecting' lugs of adjoining elements in the same sectionof a battery and at the same time servingfor the connection of elementsin adjoining sections of a battery.

Fig. 5 is a fragmentary perspective view of a few battery-elements withthe lugs of the oppositely arranged elements. individually connected. Asillustrated in Fig. 1 in the drawing, the lugs appearing commonly overthe top of the battery and heavy connections are not present in thispresent case and only the two extreme terminals 6 and 7, being the lugsto which the, line cables are customarily connected, are through the topof this battery." I 7 All the various elements of the battery areconnected below the top 8, within and between the several sections 9,9a, and 9b of the battery.

The housing of this battery is provided with 2 59 partitions 10 in thecustomary manner, depend:

ing on the number of sections desired and required for differentbatteries.

Within each section or compartment of the battery-housing a suitablenumber of batteryelements are disposed in the customary manner,

extending I Serial No. 5 82,336 f 2 Claims. (Cl. 136-'134) and it may bementioned right herethat no particular claim is made or :will bemade toany particular form ofelements as'such, exceptas to the connecting partor portion of the elements, and itqr nustbe understood that we donotlimit ourselves to any particular form of elements but only to theconnections disclosed herewith for any elements for which they may befound suited or suitable.

Instead of bridging the difierent elements of 5 each section of a wholebattery, in each of the compartments of the housing and bringing a lug Ithrough the topto be connected with a similar lug of another bridgedsection of elements in an adjoining compartment of the battery by aheavy 7 connecting member over the top of the battery, the differentelements in each section are each provided with an apertured lug 11, theapertures being designated by the numeral 12, as indicated andillustrated in Figs. 3 and 4. w

From the illustration in Fig. 5 is will be clear I that thelugs 11a ofone group of one whole sec- 7 tion of elements are arranged on one sidein the section while the lugs 11b of another group thata normally is ofthe opposite polarity in such a sec 0,

tion of a batteryis arranged on the opposite side p of the section.

Thouglr such elements are, as a rule, of cersuchdetails are notspecified here in any partic-' 5 ular form since they have no particularbearing on the principles of this invention.

The apertures in the several lugs are preferably made of tapered form,either reamed out, or

made to fit properly in any other suitable well 3 known manner, however,it is preferable that these apertures'be made, accurately to fit just asaccurately-made pins 13. The particular taper is of no great importanceas long as the pins can be pressed in, tobecome and remain tightlyengaged as battery-housing, such pins being indicatedat 13a and 13b inFig. 2.

For connecting the one groupof plates of one .110,

intersection terminals, are for this reason pro-- vided with wider lugsas indicated atllc in Fig. 4 in detail, provided with an extra hole 12for the pin 130.

Though each complete section of oppositely dis-' posed plates is as arule firmly supported Within a compartment of a battery-housing, the pin13 is nevertheless preferably made of stronger material toprevent anyundue breakage and at the same time provide for a larger wearing surfacein the hole 14 in the partition of the batteryhousing.

Having thus 7 described our invention, we c1aim:--

1. In a storage battery, a plurality of interleaved positive andnegative plates, each plate having apertured lug, the apertures in thelugs in the positive and negative plates being concentric and uniformlytapered and aligned, respectively, and tapered pins firmly disposedwithin the apertures of the plates to electrically connect the positiveand'negative plates, respectively.

2. In a storage battery, a plurality of cells, each cell comprising aplurality of interleaved positive and negative plates, each plate havingan apertured lug, the apertures in the lugs in the positive and negativeplates being concentric and uniformly tapered and aligned, respectively,tapered pins firmly disposed within the apertures of the plates toelectrically connect the positive and neg- 1 ative plates, respectively,the outermost positive plate of one cell and the outermost negativeplate of the'adjoining cell being provided with enlarged lugs havingaligned and concentric uniformly tapered apertures, and a tapered pinfirmly disposedin the apertures of the last-named lugs to electricallyconnect adjoining cells in series.
